Abstract
A secure element has a secure processor for securely processing the digital information stored in a memory external to the secure element, and a loading and pre-processing system configured to load the digital information from the external memory into the secure element, and pre-process said digital information by executing a cryptographic algorithm before processing said digital information by the secure processor. The system reads a version number of the digital information that has been loaded, from an internal memory of the secure element, and uses said version number in executing the cryptographic algorithm.
